Well, now we know Spike Lee's Twitter account is real!

We also know that fact-checking isn't his forte: The director retweeted the wrong address of George Zimmerman, the man who shot and killed 17-year-old Travyon Martin in February.  The address actually belonged to a married couple, ages 70 and 72, who have a son named William George Zimmerman -- who hasn't lived there since 1995.

The couple has been subject to harassment, media scrutiny, and threatening mail because of the mistake, and have since fled to a hotel.

This is really scary, and I'm concerned for my family, William Zimmerman told Fox News. It's scary because there are people who aren't mentally right and will take this information and run with it.

When Zimmerman appealed to the man who first tweeted the incorrect address, he was not cooperative. He reportedly tweeted back: Black power all day. No justice, no peace.

The Do The Right Thing director -- who has almost 250,000 Twitter followers -- appears to have removed the address from his Twitter feed once it was discovered to be incorrect, but does not appear to have apologized or made any public statement.

George Zimmerman, the neighborhood watch volunteer who killed Martin in Sanford, Fla. on  Feb. 26, has not been charged with the death, and is reportedly in hiding.

Martin was shot in the chest at close range by Zimmerman, who claims he was acting in self-defense, but serious questions remain about whether his use of a firearm was justified. Martin was unarmed, carrying only a pack of Skittles candy and a bottle of iced tea.

Police did not charge Zimmerman, who remained at the scene as paramedics arrived. Zimmerman did allow himself to be questioned by police on multiple occasions, including the night of Feb. 26, according to the Orlando Sentinel.

Zimmerman reportedly stood by his self-defense claim, insisting that Martin punched him in the nose, pushed him to the ground, and beat him before he retaliated. According to the Sentinel, eyewitness accounts corroborate Zimmerman's story.

On March 12, ABC News uncovered questionable police conduct in the investigation of Martin's death, including at least one instance where witness reports were edited after the fact.

Numerous petitions demanding Zimmerman's arrest are currently circulating, and multiple vigils have been held in Martin's honor. On March 21, Martin's parents joined hundreds of protesters in New York City for The Million Hoodie March, which was organized to demand Zimmerman be held accountable for the killing.

But William Zimmerman is concerned that the outrage may have gone too far in this case.

To endanger people who are innocent because people are angry is not the answer, he told Fox. That's not how we're going to heal. It's not [going] to help the Martin family for someone else to be hurt.
